Installation of the rear Addco bar is simple. Remove the 2 bracket bolts and the link arm nut from each side to remove the factory bar, and replace it with the Addco bar. This can be done in a half hour or less, and without jacking up the car or removing any wheels. Because most suspensions travel in an arc, the use of a lift or supporting the vehicle by the frame and allowing the wheels to hang can cause bar misalignment and installation difficulties. The suspension must be at static ride height for this installation.

Energy Suspension greasable bushing and clamp set for the rear sway bar. (1" version shown).

Many owners upgrade the Addco bushings supplied with the rear bar. Energy Suspension makes a set with a unique channel design and zerk fittings, allowing grease to flow to the inner bushing surfaces which prevents squeaking. The Addco supplied urethane bushings that come with the front bars are quite soft and tend to squeak. There are no aftermarket bushings available for the front bars due to the nonstandard bushing design of the front factory bushings. It's possible to make the Addco front bushings greaseable by drilling and tapping the stock metal bushing shells and adding grease fittings. You then drill a corresponding hole through the bushing for the grease to pass through.

*Important: If you are only going to upgrade the rear bar (and not the front), Addco recommends using part # 634 (7/8"). Some owners have found using a 1" Addco rear sway bar with a stock front sway bar causes the WJ to oversteer.

Front: Addco p/n 175 (1.25")

Link arm washers

1-1/4" washer with 3/4" inside diameter

Update: Some owners have reported that the washers were not needed.

Rear: 1 required for each side, may require two per side if the washers are thin. Washers should be of anti-rust material or can also be painted.

The revised 30mm solid steel sway bar with bushings will directly swap/bolt up on 1999-2003 models that came with the 31.5mm hollow bar. WJ owners who have retrofitted 1999-2003 models with the stiffer 2004 bar report a noticeable improvement.
